Good multiple RDP tool

[MasterPlan1]

I used to use mRemoteNG but it keeps screwing up on me, and it didn't have some features which I wanted. Does anyone know of a peice of software which can deal with multiple RDP sessions, and also do an AD scan of machines to import? Terminals would appear to do that, but it has been just sitting here not enumerating any results for ages. :/

Suggestions?

I would make an MMC and do it myself, would save me loads of time - but I can't author my own MMC's due to GPO restrictions.
